The present invention generally relates to a structure of a corrective shoe pads for medical purposes, and more particularly to a structure of a corrective shoe pads for medical purposes having effects of preventing eversion, ankle ligament sprain, bandy-leg, and wear of knee joint.

DESCRIPTION OF THE PRIOR ART

Human beings use two feet to stand, walk, run and moving motion. During movements, the two feet, particular the foot soles, must bear the body weight and reaction forces from the ground and they often suffer more accumulated fatigue and damage of repeated pressurization resulting from long term standing and walking than other parts of the human body. This is even more severe in case of the flat feet, high arches, or incorrect arch, which often more readily cause eversion of sole or ankle ligament sprain or even pain and hurt of knee joints.

To overcome such problems, manufacturers have developed and provided the shoe pads that helps making human feet comfortable in standing, walking , running and moving motion which own in Taiwan Utility Model M307982, which discloses a compound shoe pad for walking. This is a shoe pads of previous study and research of the present inventor and generally comprises a pad body that has the characteristics of shock absorption and back bounce and shock-absorbers are mounted to front, rear, and inner sides of the shoes body. Further, two side edges and a rear edge of the shoe pad are provided with continuously extending upward-raised support wall. As such, when a shoe is put on, the shock-absorber of the front side of the pad body corresponds to and support the transverse arch of the foot sole, the shock-absorber of the inner side of the shoe pad corresponds to and supports the medial arch of the foot sole, and the shock-absorber of the rear side of the shoe pad corresponds to and supports the heel bone of the foot sole, so as to absorb feedback shocks from the ground to protect the feet from pains caused by standing and walking, in addition to positional adjustment of portions of the foot sole to maintain body balance.

However, the compound shoe pad disclosed in the previously mentioned Taiwan Utility Model M307982 structurally does not include, at a location corresponding to the lateral arch of the foot sole, a shock-absorber to provide support to the lateral arch so that when a user is walking, standing, running and moving motion, the center of weight of the foot sole will shift outward, leading to eversion or pronation of the outer side of the foot sole. This may lead to damages such as sole fascia inflammation and ankle ligament sprain and may also affect the legs and knees of the user to cause negative situations, such as bandy legs or improper wear of meniscus of knee joints, as shown in FIG. 4.

Thus, in view of such many shortcomings of the compound shoe pad disclosed in Taiwan Utility Model M307982, the present invention aims to provide an improvement over the compound shoe pad of Taiwan Utility Model M307982.
